Abstract

Biologically inactive thyroid stimulating hormone (TSH) has been reported in hypothyroid patients. We report the first case of immunoreactive, but abnormal TSH in a euthyroid patient following hypophysectomy for a prolactin secreting pituitary adenoma. Indirect evidence indicates that this abnormal TSH was biologically inactive. The TSH was characterized by gel chromatography and has a molecular weight of approximately 23,000 daltons.
